Razzia
Self-hosted, open-source quiz platform for smaller events
Alternative to: kahoot

Razzia is a straightforward, open-source quiz platform for hosting live trivia at smaller events. A host runs the game from a manager room while players join with a PIN code and answer synchronized questions from their own devices. It supports custom quizzes, image-based questions, and even physical buzzers over a documented WebSocket protocol.
